PURPOSE: Various tumor markers, developed recently for the diagnosis of bladder cancer, are reported to be superior to urine cytology in terms of their sensitivity and non-invasiveness. A prospective study was performed to evaluate the efficacies of BTA TRAK, BTA stat, NMP22 tests and urine cytology. MATERIALS AND METHODS: Between August 2001 and December 2001, 154 patients were involved in the study. Voided urine was used to perform BTA TRAK, BTA stat, NMP22 tests and cytology. The final diagnoses were pathologically proven transitional cell carcinoma (TCCa) of the bladder in 34 patients, gross or microscopic hematuria without detectable tumor in 27, history of TCCa without evidence of recurrence in 68 and benign urologic diseases in 25. RESULTS: The sensitivities of the BTA TRAK, BTA stat, NMP22 and urine cytology were 82.4, 79.4, 61.8 and 32.4%, respectively. The specificities were 75.8, 70.8, 95.8 and 92.5%, respectively. When the sensitivity was subdivided according to the tumor stage, grade and size, the bigger size yielded higher sensitivities in the NMP22 and BTA TRAK (p<0.01 and p=0.03, respectively). When the results of the urine cytology were combined with each of the other tests, the specificity was lower than each test alone for the BTA TRAK and BTA stat, while sensitivity and specificity were both higher than each test alone for the NMP22. CONCLUSIONS: The BTA TRAK, BTA stat and NMP22 tests are useful in overcoming the limitations of cystoscopy and cytology as the initial evaluation tools for patients where bladder cancer is suspected. In particular, the NMP22 may be more useful due to its enhanced specificity when combined with the urine cytology.

Primary localized amyloidosis of the urinary tract is very rare disease. A 72-year-old man, with a history of urethral injury, had a stricture of the anterior urethra about 6cm in length. A segmental resection of urethra and urethroplasty, with penile skin flap, was performed. The resected urethral segment was diagnosed as urethral amyloidosis. There was no involvement of amyloidosis oin the other organs (heart, gastrointestinal system, joint, kidney, skin etc) and no underlying disease (multiple myelomas, rheumatism, cancer, chronic inflammation etc). Also, a 75-year-old woman, with a history of intermittent gross hematuria, had a stricture of the lower ureter. During diagnostic ureteroscopy, there was an irregular mucosal change of her lower ureter. An intraoperative biopsy showed ureteral amyloidosis. Here, we report on these two cases of primary amyloidosis of the urinary tract.

A rupture of a femoral pseudoaneurysm is an extremely rare complication of endovascular procedures, but its outcome can be life-threatening. In this report, we present a case of a femoral pseudoaneursym rupture in a patient in their early 90s following intra-arterial mechanical thrombectomy for acute ischemic stroke. Despite receiving medical and surgical interventions, the patient subsequently developed multiple organ failure, ultimately resulting in death. This case emphasizes the critical role of appropriate selection of vascular closure technique and careful post-procedural monitoring, particularly in high-risk patients.

Renal angiomyolipomas are benign mixed mesenchymal tumors, which are composed of atypical blood vessel, smooth muscle and fat cells. A 34-year-old woman presented with a palpable right abdominal mass, accompanied with discomfort. A CT scan showed a large right perinephric mass, with heterogeneous density, surrounding the kidney, with enlargement of the regional lymph nodes. The presumptive diagnosis was one of a malignant tumor of the retroperitoneum, with lymph node metastasis or an angiomyolipoma, involving both the kidney and lymph nodes. A right radical nephrectomy, including the tumor, was performed. The final diagnosis was an angiomyolipoma arising from the kidney, with the dissected lymph nodes having the same pathology. There was no evidence of a tumor recurrence during the six month follow-up period. This was an unusual case of a multicentric angiomyolipoma.

The Neuropsychiatric Inventory (NPI) is a standardized, validated, and reliable tool to assess neuropsychiatric derangements in dementia patients. The aim of this study is to develop the Korean version of the NPI (K-NPI) and to test its reliability and usefulness in dementia patients. The subjects were 49 normal controls and 92 patients with Alzheimer's disease (43), vascular dementia (32), frontotemporal lobar degeneration (11), and other causes (6). Their caregivers familiar with the subjects' everyday behavior were interviewed with the K-NPI. In a subgroup (29/141) of the caregivers, the K-NPI was repeated for test-retest reliability, average of 23.1 days after the initial test. Prevalence rates of 12 behavioral domains in dementia patients were comparable to those of the original NPI; apathy was the most common and hallucination was the least common behavior. Total K-NPI scores correlated positively with dementia severity assessed with the Korean Mini-Mental State Examination. Test-retest reliabilities of frequencies and severities of all subscales were significantly high. Depression, anxiety, apathy, irritability, night-time behavior, and eating change were identified at very low rates in normal controls and were significantly less than those in dementia patients (p<0.001). The K-NPI, whose reliability and competency are comparable to those of the original version, may be a reliable and useful tool for measuring neuropsychiatric disturbances in Korean dementia patients.

BACKGROUND: Oxidative stress might be a role in atherosclerosis and increased intake of antioxidant appear to be protective and modify neointimal formation. An antioxidant and probucol prevents endothelial dysfunction and low density lipoprotein oxidation and also inhibits the secretion of cytokine by macrophages. We aimed 1) to study the effects of antioxidant (Vitamin C, E and probucol) supplementation on serum level of antioxidant status (TAS), P-selectin, MCP-1, IL-6 and IL-10 and 2) to investigate the effects of antioxidant intake on in-stent restenosis. METHODS: Total 90 patients were assigned to control or antioxidant group (probucol; 500 mg, vitamin C; 1,000 mg, vitamin E; 400 mg). We performed follow up coronary angiography in 35 patients of antioxidant group and 36 patients of control group after 6 months of coronary bare metal stent implantation. We counted the stenotic lesions more than 50% of implanted stent lumen as a restenosis by quantitative coronary angiography. The serum levels of total antioxidant status, P-selectin, MCP-1, IL-6 and IL-10 were measured. RESULTS: The serum levels of total antioxidant status was not elevated in antioxidant group. Antioxidant supplementation did not change the serum levels of P-selectin, MCP-1, IL-6 and IL-10. The 6-month angiographic in-stent restenosis rate was 27% versus 30% (p=NS) with an associated late loss of 0.76+/-1.01 mm versus 0.91+/-1.00 mm (p=NS) for antioxidant group and control group. The serum levels of total antioxidant status did not correlate with the restenosis or late loss after stent implantation. CONCLUSIONS: Vitamin C, E and probucol did not elevate the serum level of antioxidant status and could not prevent in-stent restenosis after bare metal stent implantation.

PURPOSE: We investigated the prevalence of lower urinary tract symptoms (LUTS), and the inconvenience of each symptom, using an ICS-male Questionnaire (ICS-mQ) in Korean man. We also evaluated the relationships between symptoms, prostate volume and urodynamic parameters of a bladder outlet obstruction (BOO). MATERIALS AND METHODS: 180 male LUTS patients, from 7 urological institutions, were enrolled in this study. The ICS-mQ was used to measure the severity of the symptoms, with a bothersomeness scale. Transrectal sonography and urodynamic studies, including Schaefer linear passive urethral resistance relation (L-PURR), were performed. RESULTS: The 5 most frequent symptoms were voiding symptoms, such as reduced stream, terminal dribbling, incomplete emptying, intermittency and hesitancy, in that order. However, the 5 most bothersome symptoms included 2 voiding, and 3 storage, symptoms, such as incomplete emptying, urge incontinence, pain in bladder, nocturnal incontinence and hesitancy. 34.4% of the nocturia patients felt quite, or severely, bothered, but only 1.1% felt no problem. The mean value of estimated prostate volume, by sonography, was 29.8+/-14.1ml. There were no correlations between the severity of symptoms and the prostate size. There were also little, or no, correlations between a wide range of symptoms and the urodynamic parameters of BOO. CONCLUSIONS: The most frequent symptoms of male patients with LUTS are voiding symptoms, but they suffered more from storage, than from voiding, symptoms. The severities of the symptoms, or the bothersomeness, were not correlated with the prostate size or the urodynamic parameters of a bladder outlet obstruction. Therefore, the relief of a bladder outlet obstruction is not crucial to relieve the symptoms.

The algorithms and guidelines are a synthesis of current scientific evidences with clinical issues of safety and tolerability. It is inevitable that pharmacological strategies of psychiatric treatment have to be based on evidence-based medicine. The first Korean Medication Algorithm for Bipolar Disorder was developed from the information and opinions gathered by wide surveys to Korean psychiatrists and then, in the first time, its feasibility study was done. The problems on appropriateness of the shift of step, full education of algorithm administration and procedure before implementation, and easy applicability of measuring scales were found. These problems must be fully considered for algorithm implementation in the near future. Rapid updates on new evidences of therapeutic effects of drugs and recent trends of diagnostic concepts about bipolar disorder may justify revision of the medication algorithm. Especially, addition of widespread use of novel antipsychotics in all phases of illness, evidences of new anticonvulsants' effects, and change of strategies in the acute depression and maintenance treatments will have to be considered. Moreover, modification of questionnaire for algorithm revision will be needed in the aspect of easy implementation.

OBJECTIVE: The Korean College of Neuropsychopharmacology and the Korean Academy of Schizophrenia developed the Korean algorithm project for bipolar disorder to aid clinical decisions. The purpose of this study was to assess the treatment response and the tolerability in the feasibility testing of Korean Medication Algorithm for Bipolar Disorder (KMAP-BP) in clinical settings. METHODS: A total of 126 bipolar patients were enrolled at 17 centers. Among them, 92 patients were treated according to the algorithm. All subjects were assessed over a 4-month period. Prescribing investigators were able to change the recommended treatment strategies of the algorithm if necessary. RESULTS: Most patients showed significant decreases (p<0.001) in symptoms measured by the Young Mania Rating Scale and the 17-item Hamilton Depression Rating Scale for Depression at both assessment point 1 (about 2 weeks) and 4 months. No significant changes in adverse events were noted between baseline and endpoint. CONCLUSION: These results suggest that the treatment based on KMAP-BP can be effective and well tolerated in clinical practices. Further research is planned to revise KMAP-BP.
